With age everything accelerates. Ageing cells spread and the skin functions in slow motion. The Avène dermatological laboratories have created the Hyaluron Activ B3 serum, highly concentrated in pure hyaluronic acid (1.5%: high and low molecular weight) and niacinamide (6%) to act on the cause and signs of ageing*. Thanks to its minimalist formula containing only 8 ingredients, this serum provides a tightening effect after 15 days of use. After 15 days, the skin looks plumped, feels firmer and more elastic**: true efficiency in its purest form. Tested on sensitive skin, this fragrance-free product is suitable for all areas of the face, even the eye area. It contains: AVENE THERMAL SPRING WATER (AVENE AQUA). NIACINAMIDE. GLYCERIN. PENTYLENE GLYCOL. SODIUM HYALURONATE. ADENOSINE. CITRIC ACID. SODIUM BENZOATE
